Scintigraphy of the lacrimal ducts. Value of the lateral incidence in postoperative period

: Lacrimal scintillography, a simple, non traumatic, and physiological method, has been for a long time an useful exploration in the study excretory pathology. It allows an accurate diagnosis especially in the case of functional stenosis and, due to its ability to indicate the exact seat of obstruction, this technique is able to determine the surgical treatment required. This study underlines the contribution of lacrimal scintillography in the control of surgical anastomosis permeability, because of a modification in the initial technique: the use of scintillography in employing the lateral view rather than the front view, usually used, permits a better visualisation of the new surgically created excretory passage, particularly in the posterior area of nasal fossae.
